Technical field

The present application relates to the field of communications, and in particular, to a wireless communication method and a wireless communication device in a wireless communication system.

Background technique

In a wireless communication system, a reference signal (RS), also referred to as a pilot signal, is a predefined signal transmitted by a transmitting device to a receiving device on a predefined resource. The receiving device can obtain channel related information according to the received reference signal to complete channel estimation or channel measurement. The channel measurement result can be used for resource scheduling and link adaptation, and the channel estimation result can be used by the receiving device to demodulate the data. In general, different reference signals need to be orthogonal in order to accurately obtain channel related information. A plurality of reference signals orthogonal to each other can be generally provided by means of time division, frequency division or code division. In a long term evolution (LTE) system, an uplink reference signal includes an uplink demodulation reference signal (DMRS) and an uplink sounding reference signal (SRS), and the downlink reference signal includes a cell-specific reference signal. (cell specific reference signal, CRS), downlink DMRS, channel state information reference signal (CSI-RS), multimedia broadcast multicast service single frequency network reference signal (MBSFN) RS) and positioning reference signal (PRS). The reference signal, especially the upstream reference signal, has a low peak-to-average power ratio (PAPR) and a low raw cubic metric (RCM), which is avoided after passing through a power amplifier (PA). The reference signal is more severely altered than the data distortion to reduce the demodulation performance. Therefore, the uplink reference signal sequence in the LTE system employs a Zadoff-Chu (ZC) sequence to make the uplink reference signal have a low PAPR/RCM characteristic.

The frequency domain resources occupied by the reference signals of different user equipments (UEs) may be partially overlapped. In order to reduce mutual interference caused by partial overlapping of reference signals of different UEs, a method for transmitting reference signals is reference signal generation and mapping thereof. Position-related, the reference signal transmitted by the UE is processed by cyclic shift (CS), so that the reference signals between different UEs are orthogonal, thereby eliminating mutual interference of reference signals of different UEs. In the method of transmitting a reference signal in the technology, the reference signal generation manner sent by different UEs is independent of its mapping position, and the reference signal transmitted by the UE cannot be orthogonalized by cyclic shift, and the cross-correlation of the partially overlapping reference signals is poor, which cannot be satisfied. The needs of communication systems.

For example, the carrier bandwidth is 20 megabits (M) and the subcarrier spacing is 15 kilohertz (KHz). The carrier bandwidth includes 100 RB or 104 RB or 110 RB. The carrier bandwidth can include 1200 or 1248 or 1320. . For example, the carrier bandwidth is 50M and the subcarrier spacing is 15KHz. The carrier bandwidth includes the number of resource blocks, which can be 272RB or 275RB. The carrier bandwidth includes the number of subcarriers, which can be 3264 or 3300.

The comb is the distance of the position of the adjacent two frequency domain reference signal data mapped on the frequency domain resource. Assume that the frequency domain reference signal of length X is mapped to the subcarrier position on the frequency domain resource as x ₀ , x ₀ +K, x ₀ +2*K, x ₀ +3*K,..., x ₀ +(X- 1) *K, then the value of K is the value of the comb tooth. It is easy to know that the comb teeth are integers greater than or equal to 1, and the frequency domain reference signals are comb-shaped mapped on the frequency domain resources. Taking LTE as an example, the value of the SRS reference signal comb may be 2 or 4, that is, there is one reference signal data in two consecutive subcarriers or four consecutive subcarriers on the frequency domain resource after the frequency domain reference signal is mapped.

The minimum granularity of resource allocation is the minimum bandwidth allocated by the reference signal sequence. Taking SRS as an example, when the minimum granularity of resource allocation is 4 RBs and the allocation bandwidth is a multiple of 4 RBs, a set of ZC sequences can be used; when the minimum granularity of resource allocation is 8 RBs, and the allocation bandwidth is a multiple of 8 RBs, another Group ZC sequence.

In a communication system, the reference signal is a fixed signal that the transmitting end sends to the receiving end. Since the receiving end is aware of such a signal, the receiving end can obtain system or channel related information by processing the received signal and the signal of the transmitting end, such as channel parameters, channel quality, signal phase rotation caused by the transmitting end or the receiving end device, and the like. . There are usually two aspects to consider in the design of the reference signal: 1) what sequence is used for the reference signal; 2) how the reference signals of different users and different transmit ports are orthogonally multiplexed.

In the 5G new radio (NR) standard process, in order to solve the coverage problem, the single carrier is determined to be one of the mandatory waveforms of the uplink.

Considering that multi-user multiple-input multiple-output (MU-MIMO) in NR may occur in the case of simultaneously scheduling multiple users using single carriers, due to the allocation of user reference signal sequences of different resources Different, then multiple users using a single carrier have different reference signal sequences in the overlapping parts of the resources, and cannot use CS as a reference signal orthogonal method, but use frequency division multiplexing (FDM), time division multiplexing. (time division multiplexing, TDM) may bring a certain performance loss, and the orthogonal cover code (OCC) can only support two users.

In addition, the SRSs of different users in the same cell may partially overlap, that is, the frequency domain resources allocated by a part of the SRSs of different users may be the same. If the ZC reference signal design of the LTE is adopted, the reference signal of the overlapping part of a certain user in the same cell may be used. Interference with other user reference signals can be severe.

Users with different capabilities can access the same large system bandwidth. Take 20M system bandwidth as an example. Users of 1.4M, 5M, 10M, and 20M can access this bandwidth and allocate time-frequency resources for transmission. When users with different capabilities perform SRS transmission and use frequency hopping, since the carrier retuning requires a time interval, in general, users SRS of different capabilities can only hop in the bandwidth that they can handle. For example, a 10M capable user accesses a 20M system. The SRS of the 10M capable user can only perform frequency hopping within a 10M bandwidth, and cannot perform frequency hopping within a 20M bandwidth. At this time, users of different capabilities can access the same large system bandwidth, and simultaneously perform SRS transmission and use frequency hopping. Since users of different capabilities can only hop in the bandwidth that they can handle, after frequency hopping. The time-frequency resources occupied by the SRSs of different users may overlap, resulting in collisions and interference.

Due to the introduction of the flexible duplexing feature, two terminal devices belonging to two adjacent cells may send an uplink frame at the same time, and one downlink frame is sent. The cell edge user that sends the uplink frame will perform the neighboring cell. The downlink received user generates crosslink interference, that is, the user who is performing downlink reception may be subject to large single carrier interference. The solution to this interference can be used for interference coordination, or an advanced receiver can be used at the receiving end to eliminate interference. In the case that the user of the cell is not informed of the information of the neighboring cell and the interference information, the user of the cell can obtain the channel information of the interfering user by blindly detecting the reference signal of the interfering user, thereby using the advanced receiver to eliminate the interference. If the single-carrier reference signal still uses the LTE design, since different ZC sequences are used for different allocated resource reference signals, the blind detection should not only consider the location of the interfering user resources but also the different bandwidth allocated by the user, the number of blind detections. It will be very large.

A key point to solve the above problem is to design a ZC sequence group, by which a reference signal sequence corresponding to different allocated bandwidths can be generated, and the generation of the reference signal sequence is related to its mapping position. The cross-correlation between the reference signal sequences of the same length obtained from the ZC sequence group is improved, so that the effect of interference suppression or interference cancellation can be improved.

The present application provides a communication method for determining a ZC sequence used by a communication device according to the number of resource blocks corresponding to the system bandwidth or the number of subcarriers corresponding to the system bandwidth, thereby shortening the length of the ZC sequence corresponding to the system bandwidth, and improving the use of the system. The cross-correlation of the reference signals of different terminal devices of the bandwidth, thereby being able to reduce mutual interference of reference signals of different communication devices,

FIG. 2 shows the communication method provided by the present application. The method 200 includes:

S210. Determine a length of the ZC sequence according to the number of resource blocks or the number of subcarriers corresponding to the system bandwidth.

S220. Determine a reference signal sequence according to the length of the ZC sequence and the number of resource blocks or the number of subcarriers corresponding to the user allocated bandwidth.

The reference signal sequence is included in an uplink reference signal, and the user allocated bandwidth is a part of the bandwidth of the system.

In the method 200, the same system bandwidth may include different number of resource blocks or different number of subcarriers according to different subcarrier spacings, and different system bandwidths may also include the same number of resource blocks or number of subcarriers.

As an optional example, after the communication device determines the length of the ZC sequence according to the number of resource blocks or the number of subcarriers corresponding to the system bandwidth, a set of ZC sequences may be determined, and the communication device may determine a root according to a method in the prior art, and A ZC sequence is determined from a set of ZC sequences based on the root, and a sequence of reference signal sequences is generated from the ZC sequence that matches the allocated bandwidth of the communication device.

It should be understood that determining the length of the ZC sequence according to the number of resource blocks or the number of subcarriers corresponding to the system bandwidth is merely an example, and the communication device may also determine the length of the ZC sequence according to other parameters, such as combs.

The number of ZC sequence groups may be less than the number of combinations determining the parameters of the ZC sequence group. For example, if the carrier bandwidth includes the number of resource blocks or the carrier bandwidth includes the number of subcarriers, and the ZC sequence is determined according to the comb, the length of the ZC sequence is L, and the root set of the ZC sequence is Q=[Q(0), Q(1) , Q(2), ..., Q(Nq-1)], Nq is the number of roots. Suppose there are x kinds of carrier bandwidths including the number of resource blocks (the same x kinds of carrier bandwidths include the number of subcarriers), and there are y kinds of combs, then there are a total of x*y combinations, and each combination can determine a group of ZCs. Sequence, the length of the set of ZC sequences is the set of L roots is Q. When the length L of the x*y group ZC sequence corresponding to the x*y combination is the same between the two groups and the root set Q, the number of groups of the actual ZC sequence is less than x*y. Taking a partially identical case as an example, the same comb may be used. When the carrier bandwidth includes no more than (or less than) 100 RB, 102 RB, 104 RB, 105 RB, 106 RB, 108 RB, or 110 RB, a set of ZC sequences is used. The length of the ZC sequence of the group is L0, and the root set is Q0; when the carrier bandwidth includes more than (or not less than) 100RB, 102RB, 104RB, 105RB, 106RB, 108RB or 110RB, or when the carrier bandwidth includes the number of resource blocks When more than (or not less than) 100RB, 102RB, 104RB, 105RB, 106RB, 108RB, or 110RB and no more than 272RB or 275RB, another set of ZC sequences are used, the length of the ZC sequence is L1, and the root set is Q1.

As an optional example, taking SRS as an example, the comb can take 2 or 4, so there can be 4 sets of sequences, that is:

When the comb tooth is 2, the carrier bandwidth includes the number of resource blocks not exceeding (or less than) 100 RB, 102 RB, 104 RB, 105 RB, 106 RB, 108 RB, or 110 RB, that is, when the comb tooth size is the first value and the system bandwidth corresponds to the resource block. When the number is less than or equal to the resource block threshold, the communication device uses a set of ZC sequences, the length of the ZC sequence is L0, and the root set is Q0;

When the comb tooth is 2, the carrier bandwidth includes the number of resource blocks exceeding (or not less than) 100 RB, 102 RB, 104 RB, 105 RB, 106 RB, 108 RB, or 110 RB, or when the carrier bandwidth includes the number of resource blocks exceeding (or not less than) 100 RB, 102 RB. When the 104RB, 105RB, 106RB, 108RB, or 110RB does not exceed 272RB or 275RB, another set of ZC sequences are used. The length of the ZC sequence is L1, and the root set is Q1, where 100RB, 102RB, 104RB, 105RB 106RB, 108RB, 110RB, 272RB, and 275RB are resource block thresholds;

When the comb-tooth is 4 and the carrier bandwidth includes the number of resource blocks not exceeding (or less than) 100RB, 102RB, 104RB, 105RB, 106RB, and 108RB 110RB, another set of ZC sequences is used, and the length of the ZC sequence is L2. Set to Q2;

When the comb is 4, the carrier bandwidth includes the number of resource blocks exceeding (or not less than) 100RB, 102RB, 104RB, 105RB, 106RB, 108RB 110RB, or when the carrier bandwidth includes more than (or not less than) 100RB, 102RB, When 104 RB, 105 RB, 106 RB, 108 RB, or 110 RB and no more than 272 RB or 275 RB, another set of ZC sequences are used, the length of the ZC sequence is L3, and the root set is Q3.

It should be noted that the carrier bandwidth in the four packet cases described above includes the number of resource blocks, which can be equivalently replaced by the carrier bandwidth including the number of subcarriers, and the corresponding threshold is also replaced by the resource block value as the subcarrier value.

It should be noted that, in the four packet cases described above, the carrier bandwidth includes the number of resource blocks divided into two ranges, and when the carrier bandwidth of the user operation includes the number of resource blocks in a certain range, the range corresponding to the segment is adopted. A set of ZC sequences. Actually, the carrier bandwidth including the number of resource blocks can be divided into multiple segments. For example, if divided into three segments, a total of six ZC sequences are combined with combs of 2 or 4.

It should be noted that the values and numbers of the comb teeth in the four cases described above are only examples, for example, the value of the DMRS reference signal comb may be 1 or 2. At the same time, for different combs, the number of ranges in which the carrier bandwidth includes the number of resource block partitions may be different. For example, when the SRS reference signal is used for measurement of the direction of the beam, etc., the required measurement accuracy is not very high, so that a more sparse comb tooth such as a comb tooth size of 8 can be used for measurement, and the allocated bandwidth is a multiple of 8 RB. The number of available bandwidths is relatively small, and the number of resource blocks included in the carrier bandwidth is not segmented, that is, when the comb is 8, a set of ZC sequences are used in all carrier bandwidth configurations, and the length of the ZC sequence is L4. The root set is Q4. Thus, a total of five sets of sequences are combined with the four sets of sequences of the comb teeth 2 or 4 described above.

For example, the ZC sequence is determined according to the carrier bandwidth, the subcarrier spacing, and the comb. In this case, the carrier bandwidth and the subcarrier spacing can be used to obtain the carrier bandwidth including the number of resource blocks or the carrier bandwidth including the number of subcarriers, and then the number of resource blocks according to the carrier bandwidth. Or the carrier bandwidth includes the number of subcarriers and combs to determine the set of ZC sequences to be employed as previously described.

Other cases may similarly segment the parameters that determine the ZC sequence such that the number of groups of ZC sequences is less than the number of combinations of parameters that determine the root set of the ZC sequence.

Which set of ZC sequences can be used by implicit indication or by adding signaling indications. In the case of the implicit indication, after the user obtains the carrier bandwidth including the number of resource blocks or the carrier bandwidth including the number of subcarriers and the parameter values of the comb, the user can directly select a corresponding set of ZC sequences, and the length of the ZC sequence is L and Root set Q. In the case of adding a signaling indication, for example, there are four types of ZC sequences, the base station can use 2-bit signaling to indicate which group of ZC sequences the user specifically uses. The implicit indication and the manner of adding the signaling indication may be used in combination. When there is no signaling indicating which group of ZC sequences to use, the user selects a corresponding group of ZC sequences by means of implicit indication.

Multiple sets of ZC sequences are used, the purpose of which is to reduce the number of allocated bandwidths that can be applied to each group of ZC sequences, thereby reducing the length of the ZC sequence and obtaining better cross-correlation performance. The above DMRS reference signal comb is 1 and the comb is 2, for all allocable bandwidths of single carrier within 275 RB, the corresponding RB is 2 ^a *3 ^b *5 ^c , a ≥ 0, ^b ≥ 0, c ≥ 0, there are 53 kinds of allocatable bandwidth in each 275 RB under each comb; if only one set of ZC sequences is used, the set of ZC can generate a reference signal sequence of all assignable bandwidths when the combs are 1 and 2. When the length of the ZC sequence becomes very long, the cross-correlation correspondingly deteriorates. If each carrier bandwidth and comb configuration uses a set of ZC sequences, the number of ZC sequence groups required is relatively large, and the lengths of the corresponding ZC sequences under adjacent carrier bandwidths are not so large, that is, the performance of cross-correlation. The difference is not obvious, so the number of groups of ZC sequences is smaller than the number of combinations of parameters determining the root set of ZC sequences, which can avoid excessive number of ZC sequences, and can provide better cross-correlation performance than using only one set of ZC sequences. .

At the same time, multiple sets of ZC sequences can be used to optimize the PAPR and RCM of the reference signal allocated by the small bandwidth, and the edge coverage is improved. Taking the 4RB of the SRS as an example, the length of the corresponding reference signal sequence is 2RB and 1RB when the PAPR, RCM, K=2, and K=4 (K represents the comb) of the bandwidth optimized reference signal for 4RB, and multiple sets of root sets are used. When the comb is 2, only the reference signal sequence of 2 RB length needs to be optimized. When the comb is 4, only the reference signal sequence of 1 RB length needs to be optimized; and when a set of root sets is used, the reference signal sequence of 2 RB and 1 RB length needs to be optimized. It is difficult to find a sufficient number of roots, or the length of the ZC sequence required to find a sufficient number of roots is very long.

Hereinafter, the method of generating the ZC sequence provided by the present application will be described in detail.

Determining a set of ZC sequences according to at least one of {carrier bandwidth, number of resource blocks included in the carrier bandwidth, number of subcarriers included in the carrier bandwidth, comb, subcarrier spacing, minimum granularity of resource allocation}, and the length of the ZC sequence is L The root set of the ZC sequence is Q = [Q(0), Q(1), Q(2), ..., Q(Nq-1)], and Nq is the number of roots. The number of resource blocks corresponding to the allocated bandwidth is N _rb , which is obtained by the root set Q=[Q(0), Q(1), Q(2), ..., Q(Nq-1)] of the ZC sequence of length L. the number of subcarriers N _sc of the reference signal sequence, where N _sc is the set of elements in the N _{SC, N SC = [N SC (} 0), N SC (1), ..., N SC (N BW -1 )] is the set of subcarriers corresponding to the allocated bandwidth, N _BW is the number of allocated bandwidths, N _rb is an element in the set N _RBs , N _RB =[N _RB (0), N _RB (1),..., N _RB (N _BW -1)] is a set of resource block numbers corresponding to the allocated bandwidth. It is obvious that N _SC =12·N _RB . The number of allocated resource blocks N _rb does not exceed the carrier bandwidth. The number of allocated subcarriers corresponding to the number of resource blocks N _sc does not exceed the number of subcarriers in the carrier bandwidth or does not exceed the maximum continuous bandwidth (BP) of the UE. Number of carriers. Specifically, the allocated resource block set N _RB may be any allocatable bandwidth that does not exceed the carrier bandwidth including the number of resource blocks.

The ZC sequence is determined by the number of resource blocks included in the carrier bandwidth or the number of subcarriers and the combo of the carrier. For example, if the carrier bandwidth does not exceed 100 RBs in a comb, the same ZC sequence is used. The length of the sequence is L, and the root set of the ZC sequence is Q. Then, the resource block set N _RB corresponding to the reference signal sequence that can be generated by the ZC sequence is not all the allocable bandwidth sets including the resource block number of 100 RBs, and the number of resource blocks allocated for the uplink DMRS reference signal is 2 ^a *3 ^b * 5 ^c , so there are 34 available bandwidths for no more than 100 RBs. That is to say, from the ZC sequence whose length is L root set to Q, 34 reference signal sequences under different allocation bandwidths can be generated. It should be noted that the resource block set N _RB may be a subset of 34 allocated bandwidths. At the same time, all the assignable bandwidth sets under the current carrier bandwidth are different for different reference signals. Described above is the assignable bandwidth under the DMRS reference signal. For the SRS reference signal sequence, the allocatable bandwidth is a multiple of 4 RB, and the corresponding set of allocatable bandwidth is different from the DMRS.

For example, the ZC sequence is determined according to the carrier bandwidth, the subcarrier spacing, and the comb. In this case, the carrier bandwidth and the subcarrier spacing can be used to obtain the carrier bandwidth including the number of resource blocks or the carrier bandwidth including the number of subcarriers, and the number of allocated resource blocks N _rb does not exceed The carrier bandwidth contains the number of resource blocks.

An optional process for generating a ZC sequence is as follows:

The number of resource blocks corresponding to the allocated bandwidth is N _rb , which is obtained by the root set Q=[Q(0), Q(1), Q(2), ..., Q(Nq-1)] of the ZC sequence of length L. The number of subcarriers is a frequency domain reference signal sequence of N _sc , and the generation of the frequency domain reference signal sequence is related to the position of its mapping, where N _sc is an element in the set N _SC , N _SC =[N _SC (0), N _SC (1), ..., N _SC (N _BW -1)] is a set of subcarrier numbers corresponding to the allocated bandwidth, N _BW is the number of allocated bandwidths, N _rb is an element in the set N _RB , N _RB = [N _RB (0), N _RB (1), ..., N _RB (N _BW -1)] is a set of resource block numbers corresponding to the allocated bandwidth. The process of generating a frequency domain reference signal sequence is as follows.

The set of lengths of the reference signal sequence under the N _BW type of allocated bandwidth is expressed as M = [M(0), M(1), ..., M(N _BW -1)]. The length M _{sc of the} reference signal sequence can be obtained from the number of subcarriers N _sc and the comb corresponding to the allocated bandwidth, and M _sc is an element in the set M. The value of the comb teeth is K. It is easy to know that M = N _sc / K, that is, M = [N _SC (0) / K, N _SC (1) / K, ..., N _SC (N _BW - 1) / K].

For the subcarrier spacing K of the adjacent frequency domain reference signal data mapping position and the number of subcarriers N _sc corresponding to the allocated bandwidth, a ZC sequence x _q (n) of length L is generated from the root q and ZC sequence length L:

The root q is selected from the root set Q. It should be noted that the process of selecting a specific root q from the set Q can refer to the LTE mode. In LTE, for a length of ZC sequence, the root that can be selected is divided into 30 groups, denoted by u; each group contains 1 or 2 roots, which is called a base sequence, which is represented by v, and LTE is obtained by the user. The values of and v are used to determine the value of the particular root q to generate a reference signal. If the root set Q contains 30 roots, then corresponding to 30 groups, each group contains 1 base sequence; if the root set Q contains 30 roots, then corresponding to 30 groups, each group contains 2 base sequences, Therefore, the specific root q can be selected from the root set Q to generate a sequence by referring to the LTE method.

The maximum length of the length set M of the reference signal sequence is M(N _BW -1), and the mother sequence of length M(N _BW -1) is obtained from the ZC sequence x _q (n)

根据频域参考信号映射的位置和K以及该用户工作在载波带宽内的起始位置与载波带宽的起始位置的偏差值ΔN可以得到长度为M _sc的参考信号序列。假设频域参考信号映射的起始位置为N _ini，则长度为M _sc的频域参考信号序列r(n)可以由下式得到： The comb tooth has a value of K, and the allocated bandwidth corresponds to a sub-carrier number of N _sc . The length of the reference signal sequence is M _sc , and the sequence is

A reference signal sequence of length M _sc can be obtained according to the position and K of the frequency domain reference signal mapping and the deviation value ΔN of the starting position of the user operating within the carrier bandwidth from the starting position of the carrier bandwidth. Assuming that the starting position of the frequency domain reference signal map is N _ini , the frequency domain reference signal sequence r(n) of length M _sc can be obtained by:

In the above formula, the starting position of the subcarrier corresponding to the maximum allocated bandwidth resource is 0, and the maximum bandwidth is 100 RB, and the mapped position is 0, 1, 2, ..., 1199. The minimum starting position when K=2 may be 0 or 1, and the minimum starting position when K=4 may be 0 or 1 or 2 or 3.

It should be noted that the location of the frequency domain reference signal mapping is the location where the user maps resources within the BP bandwidth. The user works in the carrier bandwidth, and the BP bandwidth may be smaller than the carrier bandwidth. ΔN is the starting position of the user working in the carrier bandwidth. The deviation from the starting position of the carrier bandwidth. Taking the 5M BP bandwidth as the 25 RB user access 20M 100RB carrier bandwidth as an example, the starting subcarrier position of the carrier bandwidth is set to 0, that is, the 100RB carrier bandwidth subcarrier position is 0, 1, 2, ..., 1199, and the user is connected. The starting position into the carrier bandwidth is 300, that is, the BP bandwidth is 25 RB, and the user operates on the subcarriers of the location 300, 301, ..., 599 within the carrier bandwidth, and the corresponding ΔN=300-0=300.

A frequency domain reference signal sequence of length M _sc is obtained by equation (5), and then the frequency domain reference signal sequence can be mapped onto its allocated frequency domain resource, subjected to inverse discrete Fourier transform (IFFT) and a cyclic prefix added. (cyclic prefix, CP) and other operations, transmitting reference signals.

A frequency domain reference sequence of length M _sc is obtained by using equation (5), and then the frequency domain reference sequence is multiplied by a corresponding phase factor, and then frequency domain resource mapping is performed. Figure 3 shows an example where the maximum allocated bandwidth is 100 RB and K = 2. The maximum length of the corresponding frequency domain reference signal sequence is 600 subcarriers.

The length is 600. Assuming that the allocated bandwidth is 4RB, ΔN=0, and the starting position N _ini is 0, that is, the mapping position is 0, 2, 4, ..., 94, the reference signal sequence r (n) of length 48 can be determined by equation (5). )for

Assuming that the starting position N _ini is 48 (4 RB), that is, the mapping position is 48, 50, 52, ..., 142, the reference signal sequence r(n) of length 48 can be determined by equation (5).

4 is an example in which the maximum allocated bandwidth is 100 RB and K=4, and the maximum length of the corresponding frequency domain reference signal sequence is 300 subcarriers, that is,

The length is 300. Assuming that the allocated bandwidth is 4RB, ΔN=0, and the starting position N _ini is 0, that is, the mapping position is 0, 4, 8, ..., 92, the reference signal sequence r (n) of length 24 can be determined by equation (5). )for

Assuming that the starting position N _ini is 48 (4 RB), that is, the mapping position is 48, 52, 56, ..., 140, the reference signal sequence r(n) of length 48 can be determined by equation (5).

In the above description, the mother sequence is generated from the ZC sequence x _q (n), and the reference signal sequence of the corresponding length is obtained from the parent sequence. Equivalently, a reference signal sequence of length M _sc can be obtained directly from x _q (n) according to the position of the frequency domain reference signal mapping and the mapped subcarrier spacing K. Assuming that the starting position of the frequency domain reference signal map is N _ini , the frequency domain reference signal sequence r(n) of length M _sc can be obtained by:
